The pipeline infrastructure of Latin America countries, including the Republic of Ecuador, has a signifi cant accident potential. Accidence rate is facilitated by the diversity of natural and climatic conditions in the region, military-political instability in its separate parts, and imperfection of the standards for the production of pipes and equipment.The technical condition of the pipeline systems operated in Latin America for 15-20 years is imperfect. Depreciation or replacement of spent equipment and elements of the pipeline infrastructure is not being carried out at an adequate pace. Ecuador, for example, has a stable dynamics of increasing accidents at pipeline infrastructure facilities. Therefore, an assessment of the risk of the condition of the main pipelines should be carried out. Anthropogenic risk is one of the most important accident factors (50 % of all risk on main oil pipelines in Ecuador). To evaluate it, the methodology of Federal Safety Manual is proposed. The anthropogenic risk is calculated for 3 main sections of Pascuales-Cuenca pipeline, which supports with oil the provinces of Cañar, Loja, Zamora Chinchipe and Morona Santiago. For the foothill area, the specifi c probability of accidents is the most, and for the coastal and fl at areas less and equals to 0.15 and 0.14, respectively. The performed accident analysis will allow taking the necessary measuresto maintain the pipeline in working condition.

“…Furthermore, hydrazine is dangerous to both humans and the environment. In past hydrazine spills, cleanup has been monumentally difficult with largely irreversible damage to ecosystems (Kovshov, 2015). Additionally, being carcinogenic and toxic while also extremely volatile, transportation of hydrazine poses a risk to everyone involved and their surroundings (Douroudgari et al, 2021;Ingenito 2018).…”

Currently, hydrazine fuels are grossly inefficient in terms of environmentally friendliness and handling costs. Hydrogen peroxide (H2O2) and kerosene bipropellants have recently shown promise as a fuel that is similar in efficiency to hydrazine yet superior in cost and environmentally friendliness. Previous research on H2O2/kerosene bipropellants view environmentally friendliness, cost effectiveness, and fuel efficiency separately, making comparison between these properties difficult. This research uses calorimetry to provide a new method of quickly and precisely finding optimal ratios of fuels in bipropellants. For different ratios of fuel, efficiency was measured by finding the fuel mixture’s specific energy, environmentally friendliness was measured by finding the fuel mixture’s efficiency per carbon released into the atmosphere, and cost effectiveness was measured by finding the fuel mixture’s efficiency per unit fuel cost. The Cobb-Douglas function was used to optimize for multiple fuel properties at the same time: environmentally friendliness and efficiency, cost effectiveness and efficiency, and environmentally friendliness and cost effectiveness. These double optimizations brought new properties of H2O2/kerosene bipropellant fuels to light, notably that the optimal ratio of fuel for environmentally friendliness coincides with the optimal ratio for fuel efficiency, and the bipropellant remains efficacious in terms of efficiency even while operating at the optimal quantity for cost effectiveness. In short, these findings reaffirm H2O2 and kerosene bipropellants as great potential candidates for an eco-friendly and cost effective replacement of hydrazine because of their unique potential to remain environmentally friendly even at optimally efficient ratios.
